Speech audiometry can be performed using a number of tests. To mention a few the SRT (Speech Recognition Threshold) refers to the level at which the client can repeat 50% of the presented words correctly. It serves as a check of the pure tone audiogram, gives an index of hearing sensitivity for speech and helps determining the starting point for other suprathreshold measures such as WR (Word Recognition). WR is sometimes also referred to as SDS (Speech Discrimination Scores) and represents the number of words correctly repeated expressed in percent.

Most people acquire hearing aids because they or their relatives experience that they have trouble hearing speech. Speech audiometry has the advantage of employing speech signals and is used to quantify the client’s ability to understand everyday communication. It examines the processing ability and can be useful to investigate whether the processing is affected by disorders of the middle ear, cochlear, auditory nerve, brain stem pathway, or auditory centres of the cortex.
